Reaktionsschritte
A solution of 3,5-dichloropyrazine-2-carbonitrile (628 mg, 3.60 mmol), 2-(R)-amino-butanamide hydrochloride (500 mg, 3.60 mmol) and DIEA (1.60 mL, 9.20 mmol) in DMF (10 mL) was stirred at room temperature for 4 h. Water and EtOAc were added. Organic phase was separated, washed with water, dried over Na2SO4, concentrated in vacuo to give (R)-2-(6-chloro-5-cyanopyrazin-2-ylamino)butanamide (843 mg) as a semi-solid.
